Answer: I know it 4 but I don’t know the equation for it, I can only help you this far.(hope it help)
Step-by-step explanation:
(1,4) and (-2,-8)
(x is the first number of the point which is 1 and -2, y is the second number of the point which is 4 and -8.)
(x1 is 1, it alway the first point they tell you on the problem like (1,-4) is on the problem first so it gonna be x1 and y1, for x2 it -2, it alway the second point in the problem like (-2,-8) is the second point they tell you so it gonna be y1 and y2.)
Do x2 - x1 and y2 - y1(y/x)
-8 - 4/-2 - 1 = -12/-3
-12/-3 divide top and bottom by -3, that would equal to 4
Answer:
32.67
Step-by-step explanation:
18% of 181.5 is 32.67, which is much easier to solve than 181.5% of 18. It works flipped over.
<span>x = 25
(x – 7)2 = 36
(x*2) - (7*2) = 36 : multiply x*2 and 7*2 because of distributive property
2x - 14 = 36 : multiply
2x = 36 + 14 : add 14 to combine like terms
2x = 50 : add
x = 50/2 : divide 50 by 2 to get x alone
x = 25 : simplify </span>
Ok. So remember those questions you got in kindergarten example: 40 people were asked which was the nicest fruit in their opinion and here is a graph of what they thought was the nicest. So people use number bars as a way to organize problems. Does this make any sense? I will help in comments if it doesn't.
Answer:
The answer to your question is x = 19.1 y = 14.52
Step-by-step explanation:
Process
1.- Use law of sines to find x
x / sin 71° = 18 / sin 63°
- Solve for x
x = 18 (sin 71) / sin 63
- Simplification
x = 18 ( 0.946)/0.891
x = 18(1.062)
- Result
x = 19.1
2.- Find the measure of the third angle
third angle = 180° - 63° - 71°
= 46°
- Use the law of sines to find y
y / sin 46 = 18 / sin 63
- Solve for y
y = 18 (sin 46) / sin 63
- Simplification
y = 18(0.719) / 0.891
y = 18(0.807)
- Result
y = 14.52
